Limited recovery from post-acute sequelae of SARS-CoV-2 (PASC) at eight months in a prospective cohort

Abstract There is increasing recognition of the prolonged illness following acute coronavirus disease 2019 (COVID-1). In a longitudinal cohort of 99 patients, 32% reported persistent symptoms and 19% had Long COVID (Defined as fatigue or dyspnoea or chest tightness) at median 240 days after initial infection. There was no significant improvement in symptoms or measures of health-related quality of life between 4 and 8-month assessments. In multivariable analysis, female gender (OR 3.2, 95%CI 1.3-7.8, p=0.01) and acute COVID-19 hospitalisation (OR 3.8, 95% 1.1-13.6, p=0.04) were independently associated with Long COVID at 8-months. Only 80% patients reported full recovery at 8 months. Further research is required to understand the immunologic correlates of abnormal recovery and the long-term significance.
